The area of a playground is 204 yd^2 the width of thr playground is 5 yd longer that its length what the length and the width of
morpeh [17]
W= width= L+5
L= length
Area= 204

Area= LW
204 square yards= LW
substitute w=L+5 for w
204= (L)(L+5)
204= L^2 + 5L
subtract 204 from both sides
0= L^2 + 5L - 204
factor
0= (L+17)(L-12)

0= L+17
-17= L

0= L-12
12 yards= L


WIDTH
Since the area cannot be a negative number, we'll use L=12 to find the width.

w=L+5
w=12+5
w=17 yards


CHECK:
204=(12)(17)
204=204


ANSWER: The length is 12 yards and the width is 17 yards.

Hope this helps! :)

What is the effect on the graph of the function f(x) = x when f(x) is replaced with -1/2 f(x)?
inn [45]

Answer:

The correct option is B.

Step-by-step explanation:

The given function is

f(x)=x

The new function is

g(x)=-\frac{1}{2}f(x)

g(x)=-\frac{1}{2}x        .... (1)

It is in the form of

g(x)=mx                   .... (2)

Where, m is a constant.

If m is negative, then there is a vertical reflection over x-axis. If the constant is greater than 1, we get a vertical stretch and  if the constant is between 0 and 1, we get a vertical compression.

From (1) and (2), we get

m=-\frac{1}{2}

Since the value of m is negative and absolute value of m is between 0 and 1, therefore the graph g(x) shows the vertical reflection over x-axis and vertical compression.

Option B is correct.
